Miyazato and Michaels share Safeway lead
Mika Miyazato and Sydnee Michaels stayed cool in searing heat in Oregon to share the lead after the first round of the LPGA Tour's Safeway Classic.
As the mercury tipped 100 degrees at Pumpkin Ridge Golf Club the pair shot 7-under 65s to top the leaderboard by a stroke.
Sitting behind them were Cristie Kerr, Inbee Park and Pornanong Phatlum after the opening day of action in North Plains.
Last week's Toledo Classic winner Yeon Ryu was a further shot back along with Brittany Lincicome, Alison Walshe and Jee Young Lee.
World number one Yani Tseng had a 70 while defending champion Suzann Pettersen shot a 71.
Michaels made birdies on the opening four holes when temperatures were slightly cooler, although she still managed two more birdies on the final three holes.
Japanese player Miyazato said: "My golf game is very confident right now.
"To begin the season, I was not so very good with my golf game. I start to shoot right in the last couple four, five events. I'm gaining more confidence."
Mariajo Uribe delighted spectators with a hole-in-one on the 169-yard third hole on her way to finishing with 71.
